I found out that update and vector have the largest argument vector of normal defn in clojure.core (so not counting protocols, etc) (unless there's a bug in the code)
https://github.com/borkdude/grasp#find-defn-with-largest-arg-vector
They have a total of 8 arg symbols (not counting &)

TIL: update was only added in clojure 1.7

yeah i remember having to use (update-in map [key] f) before they added update

oh interesting, update-in existed from the get go. I would have totally expected that the other way around

update is a degenerate form of update-in
